Week 4

This is my brain dump for this week on things I learned, tech-related or otherwise.

Tech

• Being a visual learning, visual-based programming is intriguing. Most code is super tedious to read and lacks the aspect of visual learning that some people, including myself, lean more toward. Visualizing software itself can help with this. This already exists in many forms, Databases have visualizations for tables, UML is popular, systems architects often map out the entire system diagrammatically, and class diagrams and activity diagrams are also widely used.
  • SourceTrail is a tool that visualizes C/C++, Python, or Java codebases and lays out the dependencies and code of the repository in an interactive way. Functions, classes, inheritors, and dependencies are represented in a structured diagram
  • studio is a visual UI builder for the React framework
• Sharding can be done vertically, and horizontally. Within the particular shard, logical sharding that further segregates the data can be performed.
• Java records provide the capability to pass immutable data between classes with ease. This avoids writing lengthy boilerplate code for accomplishing the same task with final, private variables and functions for a class. Records auto-generate constructors, public getters, equals/hashcode methods, and toString method.
• make is a build system that only builds a target if the dependent input files have been modified and allow for an efficient system to build a program. make test and make release can also be used to test and release (with optimizations and building a tarball) respectively
• symantic versioning is used to version software releases. There are three parts major:minor:patch. For a change to the software that will break on older versions, the major value is incremented. All programs with the same major version and at least the same minor version (and whatever patch version) will be compatible
